[Serusers] auth_radius module problem

Hi, I have built ser and modules from the tar.gz file available on CVS. Authentication using auth_db works fine, but auth_radius results in a segmentation fault when I try to register. The debug log (with debug=9) says: Mar 22 16:21:32 voip ser: SIP Request: Mar 22 16:21:32 voip ser: method: <REGISTER> Mar 22 16:21:32 voip ser: uri: <sip:voip.pdn.ac.lk> Mar 22 16:21:32 voip ser: version: <SIP/2.0> Mar 22 16:21:32 voip ser: parse_headers: flags=1 Mar 22 16:21:32 voip ser: Found param type 232, <branch> = <z9hG4bK3378053857>; state=16 Mar 22 16:21:32 voip ser: end of header reached, state=5 Mar 22 16:21:32 voip ser: parse_headers: Via found, flags=1 Mar 22 16:21:32 voip ser: parse_headers: this is the first via Mar 22 16:21:32 voip ser: After parse_msg...
